Subject: [PATCH v2 0/8] Add some missing ABI symbols

Hi Greg,

This series contain some things I detected when using scripts/get_abi.pl.

Most of the patches here add documentation for some symbols that
were upstreamed a long time ago, but, up to today, they weren't
defined.

There are still a lot to be addressed, as, at least on my desktop, there are
8k+ undefined symbols:

./scripts/get_abi.pl undefined|wc -l
8792

Mauro Carvalho Chehab (8):
ABI: stable/sysfs-module: better document modules
ABI: stable/sysfs-module: document version and srcversion
ABI: testing/sysfs-module: document initstate
ABI: sysfs-devices-power: document some RPM statistics
ABI: sysfs-devices: add /dev ABI
ABI: sysfs-bus-pci: add documentation for modalias
ABI: o2cb: add an obsolete file for /sys/o2cb
ABI: sysfs-bus-usb: add some missing definitions
